A new study links heart health to improved cognition.
The better the heart the sharper the brain, so says the American Hearth Association in a new study.
“Dementia is commonly seen as an incurable and relentless disease that cannot be prevented,” said Dr. Fernando Testai, a professor of neurology and rehabilitation at the University of Illinois College of Medicine in Chicago.
“Evidence shows, however, that adopting a healthy lifestyle and identifying and treating vascular risk factors early may help preserve normal brain function and reduce the burden of Alzheimer’s disease and other related dementias,” said Testai, lead researcher.
Almost 130 million Americans have some form of heart disease, said AHA. Adopting a heart-healthy lifestyle early makes a difference, even before a baby is born.
This is a call to action. Many Americans already have some form of heart disease and people are getting sicker earlier in life. Too many are facing heart attacks, strokes and dementia.
The buildup of plaque is the culprit. The disease also takes a toll on the brain. The narrowing of arteries reduces blood flow and causes damage to the brain, resulting in cognitive impairment. High blood pressure and diabetes increase inflammation, leading to decline and dementia.
“Emerging evidence suggests that the bidirectional relationship between the heart and the brain is deeper than we thought,” Testai said. Atrial fibrillation is the leading cause of stroke in the US.
Focus on Lifestyle Changes
Statins help, but more is needed. There is a limit to what drugs can do. Humans are designed to live vey differently than we live today. We need to get off the couch and move.
Prioritize Sleep
Rest boosts mood, improves energy, and sharpens the brain. People who have more uninterrupted sleep do better, far better.
The Sweet Spot
When we get four to six hours of uninterrupted sleep, we thrive in the sweet spot.
Plant-based Diet
An anti-inflammatory diet of whole grains, fruits and vegetables produces the best results. Avoid red meat and ultra-processed foods, such as sugary cereals, sodas, fries and ice cream.
Benefits measurably accrue even for persons who are already battling diabetes, heart and lung problems.
Reduce Stress
Medication and deep breathing calms the body and reduces stress.
Exercise Helps
Adults who exercise 150 minutes of moderate-intensity or 75 minutes of vigorous activity each week, along with strength training see better results. This benefits the whole body, including the brain.
